If OSM cares about the share-alike part of their license, they have to successfully defend their copyright on the data. If OSM moves to open-but-not-share-alike, they no longer care if their copyright on the facts in their database is valid.

Thanks, I understand that better. I still think it's not a good argument; you seem to say that if they stopped caring about something there would be less trouble. That seems pure spinelessness.
